Zusammenfassung:	PURPOSE:To obtain a lightweight wire for a dot printer having high wear resistance and toughness by using a powdery high-speed tool steel contg. a specified percentage by area of unsolid solved carbide dispersed uniformly in the hardened and tempered matrix. CONSTITUTION:A wire for a dot printer is made of a powdery high-speed tool steel contg. >=25% by area of unsolid solved carbide dispersed uniformly in the hardened and tempered matrix. Since the wire has high wear resistance and toughness and is light in weight, increased printing speed and prolonged service life can be ensured. A chemical compsn. consisting of 1.1-4.0% C,
